AI Phrases in Academic Writing: Stock Openers, Transitions and Fixes
Short answer
Stock phrases such as "It is important to note that", "In today's fast-paced world", "plays a crucial role" and "In conclusion, this essay has explored" signal AI-like writing because they add length without adding information. Delete them and start with the point, or replace them with the specific claim they were hiding. One phrase is harmless. A page full of them is the pattern.
Key points
- Stock phrases fill space. If you delete one and the sentence still works, it was filler.
- Openers like "In today's fast-paced world" fit every topic, which is exactly why they say nothing about yours.
- Replace a transition with the relationship it should express: cause, contrast, example or consequence.
- Overusing "not only... but also" and "a wide range of" is a rhythm problem more than a vocabulary problem.
- Our detector labels about 1% of human student essays "Likely AI", so cleaning up stock phrases helps, but it is not about hitting a number.
Why stock phrases read as AI
Language models produce the most probable continuation of a sentence. For essays, the most probable openers and transitions are the ones that appeared in thousands of essays: safe, vague and reusable. Students have always used them too, which is why human essays contain them as well.
A single stock phrase is not evidence of anything. A text where nearly every paragraph begins and ends with one is far more predictable, and predictability is what detectors measure.
Openers and filler to cut
Test each phrase by deleting it. If the sentence is complete, leave it deleted.
- "In today's fast-paced world" and "In the modern digital age": delete, then begin with your actual topic or a dated fact.
- "Throughout history" and "Since the dawn of time": name the period you actually study.
- "It is important to note that" and "It is worth mentioning that": delete and state the point.
- "It goes without saying that": if it goes without saying, do not say it.
- "This essay will explore" and "This paper aims to delve into": say what you argue. "This essay argues that rent caps reduced supply."
- "There are many factors that": list the factors you will discuss.

Claims of importance without content
Phrases that say something matters, without saying why, are the second big group.
- "plays a crucial role in": say what it does. "Insulin lowers blood glucose after meals."
- "has a significant impact on": give the direction and size of the impact.
- "a wide range of", "a variety of", "numerous": give the number or name two examples.
- "various aspects" and "different factors": name them.
- "is of great importance": explain who needs it and for what decision.
- "shed light on": say what the study found.

Transitions that carry no logic
Words such as "Moreover", "Furthermore" and "Additionally" simply say that another sentence follows. A better transition tells the reader how the idea relates to the last one.
- Instead of "Moreover", write "A second cause is..." or fold the idea into the last sentence.
- Instead of "However" repeated, say "Unlike the earlier trials..." or "That result holds only for adults."
- Instead of "Therefore" after a loose argument, state the consequence: "So the policy fails for small firms."
- Instead of "Overall" or "All in all", give the one claim you most want remembered.
- Use no transition at all when two sentences follow naturally. Short, direct paragraphs rarely need them.
Closing phrases and the "not only... but also" habit
Conclusions invite the most stock language: "In conclusion, this essay has explored", "In summary, it is clear that", "Ultimately". The correct fix is to open the conclusion with your answer to the question, not a note that you are concluding.
"Not only... but also" is a perfectly good structure. It becomes a tic when it appears in every paragraph. Use it at most once or twice in an essay, and prefer two plain sentences.
Reads like AIIn conclusion, this essay has explored the many benefits and challenges of online learning, and it is clear that it will continue to play a crucial role.

Check what remains
After you edit, search your document for the phrases above and read the hits in context. Keep any that carry weight and that you would say aloud. A sentence-level detector such as AITurnitin can show which sentences still read as generic. It gives no verdict under 50 words, and the result is an estimate.
Do not use a paraphrasing tool to remove stock phrases. In our tests, AI text paraphrased by another AI model was still labelled "Likely AI" 50.5% of the time, and tools can change your meaning or break citations. Editing by hand takes minutes and keeps the text yours.
Frequently asked questions
What phrases make writing sound like AI?
Common examples are "It is important to note that", "In today's fast-paced world", "plays a crucial role", "a wide range of", "In conclusion, this essay has explored" and "not only... but also" used repeatedly. They are generic, so they add length rather than information.
Is it wrong to use "in conclusion"?
No. It is fine occasionally. The problem is a conclusion that only announces itself and restates the essay. Start with your answer or recommendation, and the phrase becomes unnecessary.
Do AI detectors look for these exact phrases?
Not as a fixed list. They estimate how predictable the overall wording is. Stock phrases contribute because they are highly predictable, but one phrase has almost no effect.
What should I use instead of Moreover and Furthermore?
Use a transition that names the relationship, such as "A second reason", "The same pattern appears in" or "This contradicts". Often you can drop the transition and let the sentences follow each other.
Can I just ask an AI to remove these phrases?
It can, but it tends to replace them with other generic phrases and may change your meaning. Delete them yourself and add the specific detail they were covering for. Check your course policy on AI editing.
